ROOFlNG-TILE.

SPECIFICATION forming part of Letters Patent No. 411,666, dated September 24, 1889.

Application filed April 16, 1889. Serial No, 307,411. (No model.)

To all whom it may concern.'

Be it known that I, ROBERT LIDD'ELL, a citizen of the United States, and a resident of Blakeman, in the eountyof Rawlins and State of Kansas, have invented certain new and useful Improvements in Roofing-Tiles; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which forni a part of this specification, and in which Figure l is a top plan view of a roof provided with my improved tiling. Fig. 2 is alongitudinal sectional view. Fig. 3 is a crosssectioual view on the line ze x, Fig. 1. Fig. 4E is a longitudinal section through line y y, Fig. l; and Fig. 5 is a detail view of the retaining-strip.

Like letters of reference denote like parts throughout the several views.

My invention has relation to improvements in rooiingtiles; and it consists in the improved construction and combination of parts, as hereinafter more fully pointed out and described, whereby when laid to form a roof they may be locked and jointed together on all sides. Further, in so constructing the eX- terior surface of the tiles as to form an effect ive nieansfor shedding the rain or moisture and preventing it from penetrating the roof and causing rotting of the rafters and string` ers or other deleterious effects thereto; and, furthermore, in various other details of construction, as hereinafter more fully described.

Referring to the drawings, the letter A indicates the rafters, and B the stringers or supporting-strips. Secured to these stringers or supporting-strips by means of bolts C or equivalents are rnyimproved tiles, designated -by the letter D, said tiles being provided at their upper ends with a V-shaped depression or recess d', and at their lower end with a correspoudiugly-shaped projection d', being provided on its under side with a shoulder or offset cl2. Each tile is also provided on its exterior surface, on one side only, with a groove d3.

In carrying out my invention a series of tiles are secured to the stringere or support ing-stri ps, so that the V-shaped depression or recess will occupy the uppermost position. Above these are then likewise placed a second series of tilesin such a manner as to permit the projection d topass into the depression d of the lower row of tiles. In this inanner it will be seen that the shoulder upon the under side of the upper t-ier will bear against the upper end of the lower tier, while the eX- tended end of said upper row will register with the depression of the lower row, thereby forming a lap-joint between the two. It will also be seen that the longitudinal grooves `upon the several tiers will register, thus forming a continuous groove. Above the grooves are arranged retainingstrips E, provided upon their under sides with longitudinal strips or tenons e, located to one side'of the center thereof, and also provided on their lower Vend with a semi-cylindrical recess c. The tenons e are adapted t-o iit into the grooves d3, said tenons being located near the edge of r,Phe strip which bears on the side of the tile in which the groove is located, thereby permitting the greater portion of the width of the strip to bear upon ,the upper surface of the adjacent strip upon that side thereof in' which the groove is not located, thus also affording ample opportunity for the insertion of bolts or equivalents F, for the purpose of securely holding said strips in place. The upper ends of these strips t in the semi-cylindrical recess in the lower end of the retaining-strip above the same, thereby interlocking and being held firmly together. The exterior surface of these tiles are formed near the upper ends thereof, from the point of the V-shaped recess or depression, with a channel G, approximately of conoidal forni, the apex thereof being located slightly below the center of the tile. By means of these channels in rainyweather the water is gathered in one stream, instead of being spread over the entire surface of the tile, until it reaches the apex of the channel, when it passes down to the next tile, where it is again gathered together in one stream, and so on until it passes to the water-spoutof the roof. f

By this construction of tile it will be seen that I am enabled to join the several tiles together in au absolutely eifective way and in ICO such a manner as to render it impossible for Water or moisture to enter and aifect the substructure, the joints being so formed as to be thoroughly protected. Furthermore, my invention is simple in construction, strong, light, and durable, and fire-proof.

By reference to Fig. 4 of the drawings it will be seen that the side groove d3 of the tiles is thickened at the point where it terminates in the projection d, while the portion of the tenons e which fits in the grooves at this point is correspondingly decreased, thus affording an even iit of said tenons within the grooves and at the same time strengthening the latter at the point where the extension projects.

Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States, is-

l. The combi11ationwith the tiles provided on oneend with a depression or recess and on theiropposite end with an undercut porvtion to forni the herein-described lap-joint between the contiguous edges of any two tiles, and being further provided on their upper Aside with a longitudinal groove, of the retaining-strips provided upon their under side with a longitudinal strip or tenon', substantially as set forth. l

2. The combination, with the tiles provided on one end with a depression or recess and on their opposite end with an undercut portion ,to4 formY the herein-described lap-joint between the contiguous edges of any two tiles, andv being further provided on their upper side with a longitudinal groove, of the retaining-:strips provided on their under side with a longitudinal strip or tenon having one' end provided with a semi-cylindrical recess,

substantially as set forth.

A 3. The combination, with the tiles provided on one end with a depression or recess and on their opposite end with an undercut portion to form the herein-described lap-joint between the contiguous edges of any two tiles, and Vbeing further provided o n their side with a longitudinal groove, of the retainingstrips provided on their under side with a longitudinal strip or tenon located to one side with a semi-cylindrical recess, substantially as set forth.

5. The combination, with the tiles provided on their upper side with a longitudinal groove,

said groove being contracted in depth at one end, of the retaining-strip provided with a longitudinal tenon fitting in said groove, the end thereof which registers wit-h the diminished or contracted portion of the groove being correspondingly decreased in width to perfect a neat joint, substantially as set forth.

G. The combination, with'the tiles providedk on one end with a depression or recess, andon their opposite end with an undercut portion to form the hereindescribed lap-joint between the contiguous edges of any two tiles, and being further provided on their upper side with a longitudinal groove, said groove diminishing' in depth at that end of the tile which is provided with the undercut portion, of the retaining-strips provided with a longitudinal tenon fitting in said groove, the portion of the tenon which registers with the reduced portion of the groove being decreased, so as to afford a perfect joint therewith, substantially as set forth. v

In testimony that I claiml the foregoing as ,my own I have hereunto affixed my signature in presence of two witnesses.
